| Abstract: | Abstract Free-cylinder pressure transducers for pressure measurements to about 1.0 GPa have been developed; they use at present foil strain gauges bonded on the cylindrical surface in order to measure strains as a function of the applied hydrostatic pressure. All such transducers can be used with thin-or thick-film gauges; distortions of the active cylinder can be measured also by optical techniques. Pressure transducers of three types (different design as to pressure full scale and cylinder materials) are described and their metrological characteristics are given as well. |
